MySQL Sum on matching set of data

This is my first post in this forum. I normally find ans to my problems when search but this is the first time I needed to post this question. Any help would be highly appreciated.

I have a table called "gjournal_main"

`dateinput` datetime NOT NULL COMMENT 'Input开发者_StackOverflow中文版 Date',
`datepaid` date NOT NULL COMMENT 'Date of Invoice',
`invoiceno` varchar(12) NOT NULL COMMENT 'Invoice #',
`bookno` varchar(12) NOT NULL,
PRIMARY KEY (`invoiceno`),
KEY `invoiceno` (`invoiceno`)

and another with transaction detials "general_journal" (or items)

`eid` int(20) unsigned NOT NULL AUTO_INCREMENT COMMENT 'Entry ID',
`tid` varchar(12) NOT NULL COMMENT 'Transaction ID or Inv no',
`ref` varchar(15) NOT NULL COMMENT 'Reference no',
`notes` varchar(30) NOT NULL COMMENT 'Narations',
`accountname` varchar(50) NOT NULL COMMENT 'AC Title',
`debit` int(12) NOT NULL,
`credit` int(12) NOT NULL,
PRIMARY KEY (`eid`),
KEY `tid` (`tid`),
KEY `ref` (`ref`)

I want to do a search on "bookno" and list all records with matching book number (eg 1254) several invoiceno can have one bookno. I want results something like this ....

------------------------------------------------------
inputdate   |invoiceno |bookno|accounttitle|debit|credit
------------------------------------------------------
2011-05-29  | 1        |1254  |item a      |12   |0
2011-05-29  | 1        |1254  |item b      |0    |3
2011-05-29  | 1        |1254  |item b      |1    |3
                             **TOTAL       |13   |6**
2010-01-06  | 2        |900   |item a      |10   |0
2010-01-06  | 2        |900   |item b      |50   |0
2010-01-06  | 2        |900   |item c      |10   |30
2010-01-06  | 2        |900   |item d      |10   |0
                             **TOTAL       |80   |30**

------------------------------------------------------

I want a break with sum of debit and credit after listing invoice number 1 and so on how can I do that ?

thanks a lot

Using union to stick a line with totals to the individual lines:

select
    g.inputdate,
    g.invoiceno,
    g.bookno,
    j.accountname,
    j.debit,
    j.credit,
    1 as recordtype /*invoice line*/
from
    gjournal_main g
    inner join general_journal j on j.tid = g.invoiceno
union all
select
    null,
    null,
    g.invoiceno,
    '** Total',
    sum(j.debit),
    sum(j.credit),
    2 as recordtype /* total */
from
    gjournal_main g
    inner join general_journal j on j.tid = g.invoiceno
group by
    g.invoiceno
order by
    bookno,
    invoiceno,
    recordtype
having
    bookno = 600
